Q 1. What makes the HI-TORQ® ring ends different from a standard ring spanner?

A. The Draper Expert HI-TORQ® 12-point ring ends are engineered to grip the flats of a fastener rather than its corners. This spreads the load across the flat faces, transmitting more torque to the nut or bolt while significantly reducing the risk of rounding the corners — particularly beneficial when working with corroded or over-tightened fasteners.

Q 2. How much movement does the ratchet mechanism allow in tight spaces?

A. The 100-tooth ratchet provides 3.6° of movement per engagement, making this spanner well suited to restricted working areas where a full swing arc is not possible.

Q 3. Why is the half moon curved shape useful in a workshop environment?

A. The curved half moon profile is specifically designed to reach around obstacles, making it easier to access fasteners that a straight spanner cannot reach. This makes the spanner particularly effective in confined engine bays and tight under-vehicle positions.

Q 4. What material and finish does the Draper 3934 spanner use?

A. The spanner is manufactured from hardened and tempered chrome vanadium steel and features a mirror chrome plate finish for corrosion protection.

Q 5. Is the 11 x 13mm spanner available as part of a set?

A. Yes. This spanner is available individually or as part of a five-piece set supplied in a wallet/roll for organised storage and transportation.

Q 6. What payment methods do you accept?

A. We accept all major credit and debit cards, along with PayPal.
